           CRYSTAL QUEST®  CQ-TN®
CQ-TN is a special purpose ion exchanger specifically designed to remove tannins, organic color, and other naturally occurring organics including organo-metallic complexes (such as heme iron) from water. CQ-TN is intended primarily for use as an organic trap in a stand-alone unit in conjunction with other ion exchange processes such as softening or demineralization. In certain situations CQ-TN can be used in the same vessel as the softener resin, as a separate upper layer. It is supplied in the chloride form as moist, tough, uniform spherical beads

FEATURES & BENEFITS
 
  • SPECIFICALLY DESIGNED TO REMOVE NATURALLY OCCURRING ORGANICS (NOM).
  • COMPLIES WITH FDA REGULATIONS FOR POTABLE WATER APPLICATIONS.
     Conforms to paragraph 21CFR173.25 of the Food Additives Regulations of the F.D.A. *
    •
  • REVERSIBLE EXCHANGE OF ORGANICS – LONG LIFE.
     Provides unequaled capability to reversibly remove naturally occurring organic matter. In this regard it is far superior to normal anion exchange resin.
  • NO FISHY ODOR
    Gives very little or no fishy odors even in applications where other resin types such as acrylics fail because of odor.
     
    *For potable water applications, the resin must be properly pre-treated, usually by a single regeneration cycle, to ensure compliance with extractable levels

OPERATING CAPACITY AND REGENERANT CONTACT TIME.

The potential throughput capability is dependent on the water analysis and the level of both sulfate and TOC. However, the actual multiple cycle operating capacity is also limited by the amount of organics that can be regenerated from the resin. At regenerant levels above 10 lbs./cu. ft. the contact time is more important than the dose level for removing organics from the resin.

Above 10 lbs./ cu. ft. dose, the amount of organics removed during regeneration will be proportional to the total contact time of the regenerant in the resin bed, including the displacement rinse (slow rinse) plus the post-regenerant soak time for up to 100 minutes. Longer contact times provide only marginal benefit. It is recommended that a minimum regenerant contact time of 60 minutes be used. If more capacity is needed, then a post-regenerant soak between the regenerant introduction and the displacement should be added.

Once the potential throughput capacity is determined, the regenerant contact time and dose required to remove the organics is determined.

For example, the formula shows the maximum available throughput for a single cycle use: These levels can only be sustained if the regeneration removes the loaded organics otherwise a lesser throughout capacity will be realized.

*CAUTION: DO NOT MIX ION EXCHANGE RESIN WITH STRONG OXIDIZING AGENTS. Nitric acid and other strong oxidizing agents can cause explosive reactions when mixed with organic materials, such as ion exchange resins.
